White Fused Aluminum Oxide Powder for Polishing crystal
1. White fused aluminum oxide description:
White Aluminum Oxide powder is made from high quality alumina by being melted above 2000 centigrade in the electric arc furnace.
It is characterized by high purity, great selfsharpening, acid and alkali resistance, high temperature resistance and stable thermal performance.
Its hardness is a little higher than brown fused alumina.
It is with low toughness, great grinding ability, small heat and high efficiency. White fused alumina can be made into all kinds of abrasives, s
uitable for grinding high carbon steel, high speed steel, stainless steel and other fine-grained abrasives; .and for polishing crystal with shinning beautiful sights

3. White aluminum oxide micropowder usage:
Suitable for various precision instrument parts polishing, ultra-precision machine tool spindle grinding and polishing crystal, super oil stone manufacturing,
ball polishing, etc. Widely used in the polishing of electronics, optical instruments, glasses, bearing,
quarts crystal, and advanced refractory material.
Details:
(1) High hardness, particle density, good single particle roundness;
(2) White, no impurities, ensuring wear-resistant layer or wear on paper color and transparency;
(3) Particle size distribution concentrated, single-particle form, minimum amount with maximum effect
(4) Selected from the melting temperature by more than 2000 degrees well made of quality white fused alumina as raw material,
